Is rtc still needed today?
Hi,
I'm administrating a pretty old solaris (2.6) system. In the cronjobs I found that every night 2 o'clock a cronjob starts /usr/sbin/rtc -c. I've never seen this app in my life before so I looked at the manpage and it told rtc is for syncing Dos and Unix Systems. Did I understand it correctly?
Is there any need today to let rtc run? What's up with the system clock on solaris systems? I'm wondering if I can remove this cronjob.
Any help would be great
cheers

I noticed in my cron log file for my solaris 8 servers the rc=1. I imagine that is return code and something did not process. Does anyone know what that is, is there fix or the implications of leaving it?
Thank you
